Abstract

PROBLEM TO BE SOLVED: To provide a remote operation apparatus having a touch operation section, configured to properly determine a single-finger move operation on the touch operation section.SOLUTION: An operation system 1 is configured by connecting a display device 3 and a touch pad 20 to a navigation device body 2. A control apparatus 4 of the navigation device body 2 is configured to determine flick or depression, on the basis of a moving speed from touch-on to touch-off positions, when a coordinate determination is notified from an operation signal output section 25 of the touch pad 20. Specifically, the moving speed is calculated on the basis of the amount of displacement from the touch-on to touch-off positions and the time required therefor. When the moving speed is equal to or higher than a threshold, flick is determined. When the speed is less than the threshold, depression is determined.

Description

  The present invention relates to an operation system including a device main body having a display device to be operated and a remote operation device for performing operation input to the display device.

  In-vehicle devices, for example, navigation devices, include a liquid crystal display device that displays a map screen and the like around the current location of the vehicle at the center of the instrument panel. In this case, a touch panel is provided on the screen of the liquid crystal display device, and a user (driver) touches the touch panel (or a mechanical switch provided in the vicinity of the screen) with a finger to guide route such as setting a destination. Various instructions are input to the navigation device, such as setting related to, scrolling the map, and changing the scale of the map.

  In recent years, in addition to the touch panel, it has been considered to provide a so-called touch pad for the user to remotely operate the display screen of the in-vehicle navigation device (see, for example, Patent Document 1). In this case, although there is no specific description in Patent Document 1, the touch pad includes a flat touch operation unit. The user moves the cursor (pointer) onto a desired icon (operation button) on the screen of the display device by tracing the touch operation unit with a finger, and presses the icon in that state, thereby pressing the icon. It can be used to select and decide.

JP2012-221387A

  Incidentally, as described above, when a touchpad is used as a remote control device for an in-vehicle device such as a navigation device, an operation such as moving the cursor as described above and clicking a desired icon is executed. In addition, various gesture operations such as a flick operation (an operation that causes one finger touching the operation surface to bend in one direction) on the touch operation unit are performed, for example, scrolling the map on the display screen Alternatively, various functions such as changing the scale of the map (reducing or enlarging) can be executed.

  However, when various gesture operations are performed using the touch pad described above, the following problems are expected to occur. That is, since the movement operation with one finger in the touch operation unit of the touch pad basically moves the cursor, even when the user performs the flick operation, the cursor is moved. For this reason, for example, when the touch pad flick operation is completed, if the position where the finger is released corresponds to the icon on the screen, the user presses the icon. There is a risk that operations that were not performed will be performed.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a remote operation device having a touch operation unit, and can reliably determine a touch operation performed in the touch operation unit. It is an object of the present invention to provide an operation system that can prevent a process unintended by a user from being executed.

  In order to achieve the above object, an operation system of the present invention includes a device main body (2) having a display device (3) to be operated, and a remote operation device (20) for performing operation input to the display device (3). The remote control device (20) includes a flat touch operation unit (21), and a user in the touch operation unit (21) uses a finger or a touch pen. The device main body (2) includes a signal output means (25) for detecting the touch-on and touch-off operations and the position of the touch-off and touch-off, and outputting an operation position signal. ) Is provided with an operation determination unit (4) for determining a user operation based on the operation position signal notified from the operation position signal, and the operation determination unit (4) Based on the moving speed of the touch position to Luo touch-off, having characterized in that it discriminates flick operation if pressing operation (the invention of claim 1).

  Here, in general, when the user performs, for example, an operation with one finger on the touch operation unit (21), or when the user performs an operation of pressing an icon on the screen without moving the finger, the touch-on position and the touch-off position are displayed. Depending on the position, there is no or almost no change in position. When a cursor movement operation is desired on the screen, the finger is shifted from the touch-on position to the touch-off position, but the movement speed of the finger (touch position) at this time is relatively slow. On the other hand, when performing a flick operation, the finger is moved relatively quickly after touch-on, and the touch-off operation is performed in a short time.

  In the present invention, when there is a user operation on the touch operation unit (21) of the remote operation device (20), the signal output means (25) detects the touch-on and touch-off operations and their positions, and the operation position signal is output. Output to the device body (2) side. In the device main body (2), the operation determination unit (4) determines the user's operation. The operation determination unit (4) determines the touch position from the touch-on to the touch-off in the touch operation unit (21). It is determined whether the flick operation is a pressing operation based on the moving speed. Therefore, according to the present invention, there is provided the remote operation device (20) having the touch operation unit (21), and the touch operation performed in the touch operation unit (21) can be reliably determined. Thus, it is possible to prevent a process unintended by the user from being executed.

The control device 4 detects the current position (absolute position), traveling direction, speed, travel distance, current time and the like of the host vehicle based on inputs from the sensors 12 to 15 constituting the position detection unit 5. It is like that.

  The map database 6 stores, for example, road map data all over Japan, destination data such as various facilities and stores, data for map matching, and the like, and functions as map data acquisition means. The road map data consists of a road network in which roads on the map are represented by lines, and is given as link data in which intersections, branch points, etc. are divided into a plurality of parts as nodes and the parts between the nodes are defined as links. . This link data includes link-specific link ID (identifier), link length, link start point, end point (node) position data (longitude, latitude), angle (direction) data, road width, road type, road attribute, etc. Consists of data. Data for reproducing (drawing) the road map on the screen of the display device 3 is also included.

  The display device 3 is composed of, for example, a liquid crystal display capable of color display, and the screen displays, for example, a menu screen or a map screen (see FIG. 4) when the navigation function is used. At this time, the control device 4 controls the map display of the display device 3 based on the vehicle position detected by the position detector 5 and the map data of the map database 6. Therefore, a map display function is realized from the display device 3, the control device 4, the map database 6, and the like, and the navigation device body 2 has a map display function. Further, the user can perform various inputs and instructions by touching the touch panel 11 on the screen of the display device 3. The audio output device 8 includes a speaker or the like, and outputs music, guide audio, and the like. The communication device 10 transmits / receives data such as road information to / from an external information center.

  Thus, as is well known, the navigation device body 2 (the control device 4) can display a location function for displaying the detected position of the host vehicle together with the road map on the screen of the display device 3, or a destination designated by the user. The navigation processing such as a route guidance function for searching for and guiding an appropriate route is executed. At this time, the route search is performed using, for example, a well-known Dijkstra method. As is well known, the route guidance is performed by outputting necessary guidance voice by the voice output device 8 together with the screen display of the display device 3.

  FIG. 4 shows a display example of a navigation screen (map display screen) of the display device 3, where the current position and traveling direction of the host vehicle are displayed superimposed on the road map screen. During the execution of the route guidance function, recommended routes to be traveled are displayed and guided. Further, a cursor C (pointer) is displayed on the screen of the display device 3, and a plurality of icons I (operation buttons) for inputting various functions are displayed.

  In this embodiment, as shown in FIG. 1, the touch pad 20 as a remote control device has a rectangular flat plate shape (panel shape) as a whole, and a touch operation unit 21 is provided on the surface (upper surface). Is provided. In the present embodiment, the touch pad 20 is provided with, for example, three operation keys 22, 23, and 24 side by side. The three operation keys 22, 23, and 24 are, for example, sequentially from the left, a “map display” operation key 22, a “return” operation key 23, and a “decision” operation key 24.

  As is well known, the touch operation unit 21 is configured by arranging electrodes in a matrix in a X-axis direction and a Y-axis direction on a flat sheet, and is operated by a finger of a user's hand (or a touch pen or the like). A touch operation including touch-on and touch-off on the surface and its position (two-dimensional coordinates) can be detected. As the detection method, either a resistance film method or a capacitance method may be used.

  As shown in FIG. 2, the touch pad 20 is a signal that outputs to the control device 4 an operation position signal that is touched by the touch operation unit 21 and an operation signal of the operation keys 22, 23, and 24. An operation signal output unit 25 as output means is provided. In the present embodiment, the touch pad 20 and the navigation apparatus body 2 are connected to each other via a cable, but they are connected by wireless communication such as Bluetooth (registered trademark). May be performed.

  The user can give various input instructions to the navigation device body 2 (display device 3) by various gesture operations including touch-on and touch-off operations on the touch operation unit 21 of the touch pad 20 in the same manner as the operation of the touch panel 11. it can. In this case, examples of the gesture operation performed by the user on the touch operation unit 21 include, for example, an operation surface pressing operation, a drag operation (an operation for shifting a finger (one finger) touching the operation surface), and a flick operation ( Operation that moves the finger touching the operation surface in one direction), pinch-out operation (operation that moves the two fingers that touch the operation surface away), pinch-in operation (two fingers that touch the operation surface) To move them closer to each other).

  Thus, when the touchpad 20 is operated by the user, as described above, the type of gesture operation including touch-on and touch-off of the touch operation unit 21 by the user from the operation signal output unit 25 to the control device 4, Operation position signals such as the operation position (coordinates), movement direction, and movement amount are output (notified). The control device 4 functions as an operation determination unit that determines the user's operation from the operation position signal notified from the operation signal output unit 25 of the touch pad 20, and performs various input setting processes according to the determination. At this time, as a matter of course, a correspondence relationship is set between the two-dimensional coordinates of the touch operation unit 21 and the two-dimensional coordinates of the screen of the display device 3. Further, the control device 4 has a timer function that counts the time in the gesture operation (the time until the next operation, etc.).

  For example, when a navigation screen (map display screen) as illustrated in FIG. 4 is displayed on the display device 3, the control device 4 performs the following control (operation) based on the operation of the touch pad 20. . That is, when a pressing operation of the touch operation unit 21 (an operation in which touch-off is performed after a predetermined time while there is almost no movement of the touch position from touch-on) is made, a coordinate determination notification regarding the operation position is made. Therefore, when the cursor C at that time is positioned on any icon I, the operation (determination) of the icon I is performed.

  Further, when the touch operation unit 21 is dragged, the cursor C is moved in the moving direction (and moving amount). When the flick operation of the touch operation unit 21 is performed, the screen is scrolled in the direction of the flick operation on the map screen. At this time, when a touch-off in the flick operation is detected, a coordinate determination notification regarding the position is made. Furthermore, when the pinch-out and pinch-in operations of the touch operation unit 21 are performed, the scale of the map is changed, that is, enlargement (details) and reduction (wide area) are performed.

  At this time, as will be described in detail in the following description of operation (flowchart description), in this embodiment, the control device 4 starts from touch-on when a coordinate determination notification is made from the operation signal output unit 25 of the touchpad 20. Based on the moving speed of the touch position until touch-off, it is configured to determine whether the flick operation is a pressing operation. More specifically, the movement speed is calculated from the amount of movement of the touch position from touch-on to touch-off and the time required, and when the movement speed is equal to or greater than the threshold value, it is determined that the operation is a flick operation, and the threshold is reached. If it is less than the value, the committee determines that the operation is a pressing operation.

  Next, the operation of the above configuration will be described with reference to FIG. As described above, the user (driver or other occupant) can remotely operate the screen of the display device 3 by operating the touch operation unit 21 of the touchpad 20 at hand. In this case, the icon I can be selected (determined), the map screen can be scrolled, or the map screen can be enlarged or reduced by various operations of the touch operation unit 21 of the touch pad 20.

  By the way, when various gesture operations are performed using the touch pad 20, the movement operation with one finger in the touch operation unit 21 basically moves the cursor C. Therefore, the user performs the flick operation. Even when the operation is performed, the cursor C is moved. Therefore, when the flick operation of the touch operation unit 21 is completed, if the position where the user releases the finger (touch off) corresponds to, for example, the icon I in the upper right part on the screen, a coordinate determination notification is made. Therefore, there is a possibility that the pressing operation of the icon I is performed. That is, the user's operation on the touch operation unit 21 may be erroneously determined, and an operation that the user did not intend may be performed.

  Therefore, in this embodiment, the control device 4 executes the operation determination process shown in the flowchart of FIG. 3 when there is a coordinate determination notification from the operation signal output unit 25 of the touch pad 20. That is, first, in step S1, when there is a coordinate determination notification from the operation signal output unit 25 of the touch pad 20, in step S2, the position in the coordinate determination notification from the position of the cursor C at the time of touch-on (touch-off position). The moving speed is calculated from the amount of movement up to and the time required from touch-on to touch-off.

  In the next step S3, it is determined whether or not the calculated moving speed is greater than or equal to a threshold value. If the moving speed is equal to or higher than the threshold (Yes in step S3), it is determined in step S4 that the coordinate determination notification is a flick operation. On the other hand, if the moving speed is less than the threshold value (No in step S3), the coordinate determination notification is determined to be a map pressing operation in step S5.

  Here, in general, when the user performs an operation with, for example, one finger on the touch operation unit 21 or performs a pressing operation, the position change is 0 or 0 with no finger movement between the touch-on position and the touch-off position. There is almost no state. Further, when it is desired to move the cursor C on the screen, the finger is displaced from the touch-on position to the touch-off position, but the movement speed of the finger (touch position) at this time is relatively slow. On the other hand, when performing a flick operation, the finger is moved relatively quickly after touch-on, and the touch-off operation is performed in a short time.

  Therefore, as described above, based on the moving speed of the touch position from the touch-on to the touch-off in the touch operation unit 21, it is determined whether the flick operation is a pressing operation, and thus the operation intended by the user can be performed with sufficient certainty. Can be determined. As a result, according to the operation system 1 of the present embodiment, the remote operation device 20 including the touch operation unit 21 is provided, and the touch operation performed in the touch operation unit 21 can be reliably determined. It is possible to obtain an excellent effect that it is possible to prevent a process unintended by the user from being executed.

  In the above embodiment, the present invention is applied to the control of the display device in the vehicle-mounted navigation device. However, the present invention is not limited to this, and can be applied to the control of various devices (operation objects). it can. Moreover, although the said Example demonstrated operation with the finger with respect to the touch operation part of a touchpad, it is applicable also to operation with a touch pen. In addition, the remote control device (touch pad) may not be provided with an operation switch, and the present invention can be appropriately modified and implemented without departing from the gist.
